When she retired to her own room, the little fortitude, which had supported her in the presence of her relation, forsook her; she remembered only that Valancourt, whose character appeared more amiable from every circumstance, "that unfolded it", was banished from her presence, perhaps, for ever, and she passed the time in weeping, which, according to her aunt’s direction, she ought to have employed in dressing. 

그녀가 자신의 방으로 돌아갔을때, 그녀의 친척 앞에서 그녀를 지지해줬던 작은 용기는 그녀를 저버렸다, 그녀는 어떤 상황에서도 쾌할하고 상냥한 모습이었던 발랑 쿠르가 그녀의 앞에서 아마도, 영원히, 사라졌다는 사실만을 기억했고, 이모의 지시에 따라 옷을 입을때 눈물을 흘렸다. 

여기서 "that unfolded it"을 어떻게 해석하는게 좋아?
